Description
Technical field
The present invention relates to the locking mechanism of mechanical connection, particularly relate to a kind of self-locking folder.
Background technology
Bicycle is as a kind of important vehicle, always welcomed by the people since appearance.Folding bicycle is little due to volume after folding, deposits convenient transportation, has more preceence, rides instead of walk and one of important instrument of body-building so folding bicycle becomes people gradually.General folding bicycle or battery-driven car are all realize folding by folder, folder also claims hinge locking device, with the development of folding bicycle, existing folder great majority adopt the device being similar to clamping pin mechanism to realize fastening self-locking, but this device is when bicycle is sealed, motive force between the vehicle body of front and back or propelling thrust all concentrate on bayonet lock, bayonet lock is easily out of shape under the concentrated load effect of such power, be not easy after folding to launch, after long-time use, fasten position and easily become lax, whole folder is not easy to launch and fold.
A kind of firmly self-locking folder how is provided to be industry technical matters urgently to be resolved hurrily.
Summary of the invention
The object of the invention is the defect existed for above-mentioned prior art, propose a kind of self-locking folder.
The technical solution used in the present invention is, design a kind of self-locking folder, comprise: the front connector that one end is hinged and rear joint, the hinged one handle of free end of described rear joint, described handle upper portion is provided with a locating dowel pin, a tight lifting pin is fixed in bottom, described locating dowel pin is provided with the pipe link of keyhole through a upper end, described pipe link lower end screw thread docks described tight lifting pin, pipe link is also provided with a hook with safety tong mechanism, the free end of described front connector is provided with self-locking boss, and this self-locking boss and hook with safety tong mechanism coordinate and realize the closed and locked of front connector and rear joint.
In one embodiment, described hook with safety tong mechanism comprises: the self-locking card locked with described self-locking convex decometer be placed on the sleeve pipe on described pipe link, be provided with the square latch of this casing part, be located at these square latch both sides, be located at described sleeve pipe side and extend to a push button outside handle, be located at a spring that is in this sleeve pipe and that be enclosed within described pipe link, with the annular shaft shoulder on pipe link, the two ends of this spring are limited bottom the inner circle of sleeve pipe.
Self-locking boss in described front connector is corresponding with self-locking card to be arranged, and the outside of self-locking boss is cambered surface; The front connector of corresponding described square latch has the groove coordinated with square latch.
The lower end of described pipe link is also provided with the banking stop limiting described square latch and move down.
Compared with prior art, the hook with safety tong mechanism that the present invention adopts is enclosed within connecting rod, and a pair self-locking card being arranged on square latch both sides can fasten mutually with self-locking boss.This structure stress is reasonable, self-locking is more reliable, and extends service life.Front connector is opened groove square latch is embedded wherein, and can not to rotate, thus to ensure that self-locking card does not also rotate, so that self-locking card and self-locking boss accurately fasten.The lower end banking stop being located at pipe link can also limit the citing that square latch moves down, to ensure that self-locking card and self-locking boss accurately fasten.The present invention can realize auto-lock function, and structure is simple, easy to use.
Accompanying drawing explanation
Fig. 1 is schematic perspective view of the present invention;
Fig. 2 is section-drawing of the present invention;
Fig. 3 is the structural representation of hook with safety tong mechanism of the present invention;
Fig. 4 is the structural representation of front connector of the present invention.
Detailed description of the invention
Below in conjunction with drawings and Examples, invention is described in detail.
As shown in Figure 1, 2, the self-locking folder that the present invention proposes comprises: front connector 1, rear joint 2 and handle 3, and wherein front connector 1 is hinged with rear joint 2, and handle 3 is hinged with the free end of rear joint 2.Handle 3 top is provided with a locating dowel pin 4, a tight lifting pin 5 is fixed in bottom, a pipe link is fixed between locating dowel pin 4 and tight lifting pin 5, locating dowel pin 4 is through the keyhole of pipe link 6 upper end, pipe link 6 lower end screw thread docking tight lifting pin 5, and being arranged with a hook with safety tong mechanism, the self-locking catch 7 that the free end of front connector 1 is provided with, this self-locking catch 7 fastens hook with safety tong mechanism and realizes front connector 1 and rear joint 2 is closed and locked.
As shown in Figure 3,4, hook with safety tong mechanism comprises one and is enclosed within sleeve pipe 8 on pipe link 6, the bottom of sleeve pipe 8 is provided with square latch 801, the lower end of pipe link 6 is provided with the banking stop 9 limiting square latch 801 and move down, pipe link 6 is arranged with spring 10, with the annular shaft shoulder 13 on pipe link 6, the two ends of this spring 10 is limited bottom the inner circle of sleeve pipe 8; Square latch 801 both sides are provided with the self-locking card 11 with self-locking boss 7 kayser, and the side 701 of self-locking boss 7 adopts cambered surface.The front connector 1 of corresponding square latch 801 has the groove 101 coordinated with square latch 801.Sleeve pipe 8 extends to outside handle 3 and have a push button 12, the side of handle 3 is provided with moving up and down of slotted engagement push button 12.
During concrete use, consult Fig. 1, Fig. 2, first, folder from latching operation, front connector 1 and rear joint 2 first fold, again by handle 3 up time upwardly, pipe link 6 drives the self-locking card 11 of hook with safety tong mechanism along self-locking catch 7 cambered surface 701 upward sliding simultaneously, in sliding process, whole hook with safety tong mechanism also passively upwardly, sleeve pipe 8 coordinates the annular shaft shoulder 13 Compress Spring, after slip puts in place, self-locking card 11 moves down with self-locking boss 7 sealed by the antagonistic force of spring 10, Latch lock is closed in front connector 1 and rear joint 2, after the groove 101 that handle 3 side and square latch 801 snap in, before limiting, the upper and lower mutual dislocation of rear joint moves.The second, unfolded device operation, now only needs upwards to stir push button 12, and like this, self-locking card 11 and self-locking boss 7 depart from mutually, and 3, handle can outwards swing the inverse time, thus remove self-locking, unfolded device, whole simple operation.After unclamping, spring 10 is also stretched out, and now, hook with safety tong mechanism slide downward, in order to prevent sleeve pipe 8 from departing from spring completely, the banking stop 9 of setting limits the downslide of square latch 801, and keeps the proper height of hook with safety tong mechanism.
Above-described embodiment is only for illustration of the specific embodiment of the present invention.It should be pointed out that for the person of ordinary skill of the art, without departing from the inventive concept of the premise, can also make some distortion and change, these distortion and change all should belong to protection scope of the present invention.
